The severity of a 22mm nodule in the lung is closely related to the benignity or malignancy of the nodule, if it is malignant, the situation is more serious.
The main types of nodules are ground glass nodules, partially solid nodules and solid nodules. Ground glass nodules smaller than 5mm are mostly benign, while nodules larger than 8mm need to be considered as early stage lung cancer, which can be further examined by enhanced CT of the chest and percutaneous lung puncture to make a clear diagnosis.
When the lung nodule is 22mm, the possible conditions are tuberculous ball, inflammatory pseudotumor, early lung cancer, etc.. If it is accompanied by burr-like, lobulated, etc., as well as the presence of pleural pulling sign and pleural depression sign, etc., the possibility of early lung cancer needs to be considered. If enhanced CT suggests calcification, it may be tuberculosis ball. If percutaneous lung puncture suggests granulomatous changes, it may be an inflammatory pseudotumor.
It is recommended to go to a regular hospital for timely consultation when a 22mm lung nodule is found, and cooperate with the doctor to improve the relevant examinations.
